1 Claim. l

,The` presentinventionrelates to Window sash construction and has for its main object the provision of novel means for joining horizontal and vertical sash bars.

A still further object of the: present invention is-the provision of. an interlocking joint between vertical and horizontal sashbars, and which` are constructed partially of `wood and partially of metal;

Astili further object of the present invention is the provision of a suitable joint between vertical and horizontalv sash bars, and wherein the sash bars are constructed. ofxwood and lined .with metallic.. plata, and. inwhich. joint. the wooden part oi the sash bars as well as of the metallic lining plates are interconnected.

With the above general objects in view an others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of` parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part of this application `and in which like designating characters refer to corresponding parts throughout the several views:

Fig. 1 is an elevational face view of a window sash;

Fig. 2 is an enlarged cross-sectional View on line 2-2 of Fig. 1; and

Fig. 3 is a cross-sectional view on line 3-3 of Fig. 1.

Referring in detail to the present drawing, there is shown therein a window sash frame generally indicated by IIl, and which has a pair of spaced vertical sash bars II and a pair of horizontal sash bars I2. Said vertical and horizontalsash bars are suitably interconnected to form joints at the corners of the sash, and which joints are the subject-matter of the present invention. Y

Each of said sash bars, made of wood, is lined by metallic plate I 3. Said metallic plates of each pair of the sash bars II and I2, and adjacent one side of the window sash, and inwardly thereof, are doubled upon themselves to effect window pane retaining flange I4. Portions oi said flange I4 adjacent each sash bar is beveled at its end as at I5, 'and the ends of said portions of flange I4 of each adjacent sash bars II and I2 are joined by angular metallic plate I6 and rivets I'I or the same, if preferred, may be soldered or welded.

The wooden parts of each vertical sash bar are reduced to eifect an integral central tongue I 8.

bars IIL, adjacent said tongue |18 are undercut to eifect4 tapers: I9a The` endsA of said tongues` IB` eachV has` an.y angular' groove 28.

The ends: of said horizontal sash bars I2 are recessed for dening a pair offfspaced railsi2I", at each corner of` the window sash, withinwhich tongue. I8 is receivable,...asisclearly seen in7 Fig. 3.

'lfd` retain cover plates' I3Iof `sash bars IiI 'and :I2, within. thejoint thus formed by `tongue i8. and. rails 2.1i within eachl cornenof'the window sash. I0, saidfcover platesr I3; both. in, the horizontal and vertical. bars, arasuitably` formed whereby said; cover plates. I3` may`r enter said'. joint and; beinterlo'clred'.therein.v To, accomplish this.. pur--v` pose, cover plate I3 of each of the vertical sash bar II and at each end thereof, is angularly bent, as at 22 to conform with and overlie said tapers I9. Thereupon said cover plate I3 of the vertical sash bar II, on both sides thereof is angularly bent in a vertical direction, for defining a pair of spaced iiaps 23 which overlie the two faces of tongue I8 as is clearly seen in Fig. 3.

Each rail 2I at each corner of the joint is downwardly beveled in opposite directions to conform to the tapers I9 of the vertical sash bars I I.

Cover plate I3 of horizontal sash bars I2 and at each end thereof, is likewise suitably formed to conform to theoutlines of rails 2 I, namely said cover plate I3 at each face of said horizontal sashbars I2, and adjacent the upper and lower beveled edges of said rails 21|, is angularly bent to define a pair of substantially parallel lips 24. The pair of inner opposed lips 24 is positioned between the adjacent beveled portions of said rails 2| and the tapered portions of metallic plate I3 of vertical sash bars II, wherein they p are retained, while the outer pair of opposed lips 24 line the beveled faces of the outer edges of said rails 2|, and constitute continuation of `groove 20 made in tongue I8. The body portion of each horizontal sash bar I2 and between the joints formed therebetween and said vertical sash bars II are likewise groovedfto provide a continuation of groove defined by groove 20 and outer pair of lips 24, for receiving therewithin angular strips 25, which are maintained in position'by a plurality of screws 26 passing through said strips 25 and engaging the wooden bodyl portion of horizontal sash bars I2 between the corner joints hereinabove described. Thus said strips 25 maintain the outer pairs of lips 24 concealed within the joint and in contact with the adjacent beveled faces of rails 2|.

A plurality of rivets 21 passed through each corner of window sash I and thereby through each tongue I8 and its cooperating pair of rails 2l, maintain the wooden portions of the several sash bars as well as the interlocked portions of plate I3 in 'a rigid position.

From the hereinabove description it will be yapparent that the beveled portions I9 of plate I3 at the vertical sash bars II and flaps 23 are tucked and embedded between tongue I8 and rails 2l. The inner pair of tapering lips 24 contact with land overlie the outer faces of said beveled portions I9, while the outer pair of said tapering lips 24 is engaged by strip 25. By virtue of this construction plates I3 of the horizontal and vertical sash bars at the corners of window sash I0 are maintained in a rigid interlocked position. Tongues I8 and rails ZI 'are also maintained in a rigid interlocked condition, thereby preventing separation or displacement of the latter due to warping, swelling or other causes.

faces of said tongue, an end of the other of said bars having spaced rails between which said tongue fits, the edges of said rails adjacent the base of the tongue being inclined in parallelism with said shoulders and the edges of said rails adjacent the free end of the tongue being inclined*` a clamped interlocked relation with said first Y vnamed bar.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may he made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

A joint for a pair o-f fibrous bars, said bars having both sides thereof lined with a metallic plate, comprising a centrally disposed tongue of reduced thickness at an end lof one of said bars, there being an angulargroove along the free end of the tongue fand inclined shoulders at the base thereof which shoulders overlie said tongue, the metallic plate lining the last named bar onhoth faces thereof also lining said shoulders and both STANLEY GALUSKA.
